Evermore Heights mains (scheme) connection

Find out more about the connection of irrigation systems in Evermore Heights to our mains (scheme) water supply.

What is happening?

Since 1 September 2016, Evermore Heights residents have had control over the amount of water used on the garden due to the end of the third pipe irrigation scheme trial. A close out report was produced which evaluates the objectives set at the establishment of the scheme and examines the lessons learnt from operating and closing down the scheme.

Satterley Property Group arranged for garden reticulation to be disconnected from the third pipe scheme to our mains (scheme) water supply. The scheme already supplies water to the rest of your household and property.

What support is available to assist me through this change?

To assist account holders through this change, a one-off $242 credit was shown on Evermore Heights’ property water bills. This is the equivalent of a 1 year supply of garden water and is based on Perth's annual average water consumption of 120,000L for garden/outdoor use.

Additional costs such as groundwater licencing fees, and the duplication of water supply infrastructure made the scheme very expensive to install and operate when compared to the benefits it delivered.

The third pipe scheme was installed in good faith as and all partners hoped it would provide a breakthrough in sustainable water management practices. Unfortunately, in this case the scheme was found not to be viable to continue.

The developers ran a number of free 'Sustainable Living' workshops throughout the development to promote waterwise practices. However, a requirement for additional communication and education may be a learning from the Evermore Heights scheme.

While water use was a factor in the decision, it wasn’t the only factor. The scheme was not viable.
